Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...

Introduction: Nowadays, radioisotopes have a lot of therapeutic and diagnostic applications in nuclear medicine. The technetium-99m radioisotope is widely used in the diagnostic field. The technetium-99m radioisotope is widely used in the diagnostic field. In this study, in order to increase the absorption dose in thyroid cancer cells, the radioactive drug technetium-99m which ...

Objective(s): Cancer diagnosis in its early stages of progress, can enhance the efficiency of treatment utilizing conventional therapy methods. Non-biocompatibility of iron oxide nanoparticles (IONPs) has made a big challenge against their usage as a contrast agent. Efficient coverage by biomolecules such as albumin can be a solution to overcome this problem. Herein, albumin-coated IONPs were p...

BACKGROUND The aim of this study was to evaluate the image quality and radiation dose of CT coronary angiography (CTCA) with low kV, low concentration contrast agent, and iterative reconstruction. MATERIAL AND METHODS Ninety cases were randomly divided into 3 groups according to contrast agent concentration: group A 270 mg/ml (100 kV), group B 350 mg/ml (120 kV), and group C 370 mg/ml (120 kV),...

In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...
